Traditional Fibre optic cable propagate light along straight lines

Traditional Fibre optic cable propagate light along straight lines, however this new technology focuses of sending beams of light in a donut shape laser light beam called optical vortices which twists like a tornado as it moves along the fibre optic cable SFP+ Cables.Optical vortices, also known as Orbital Angular Momentum (OAM) beams are nothing new and have been studied in depth in atomic physics, quantum optics and even molecular biology. OAM beams were thought to be unstable inside a fibre optic cable, however a new research paper published by BU Engineering Professor Siddharth Ramachandran along with USC’s Alan Willner demonstrated that not only could these beams be made stable inside a fibre optic cable but could potentially be used to boost internet bandwidth.
Both Ramachandran and Willner collaborated with OFS-Fitel and the Tel Aviv University in order to test their findings and the project was funded by the Defence Advanced Research Project Agency. Their breakthrough could not have come at a better time as the massive proliferation of mobile devices has led to a sudden demand for higher bandwidth on a world wide scale. Traditionally, fibre optic cable enhanced their bandwidths by increasing the number  pure glass of colours (or wavelengths) in their laser signals. These signals consist of 1s and 0s which are sent down the fibre optic cable where they are processed according to each colour. Thru the 1990s, this method has worked well, however it is now reaching its physical limits.
